modulation signal frequency

基本解釋

Also, the effects of the interference group-delay and modulation signal frequency are discussed.
分析了主通道群延遲與調(diào)制頻率對(duì)對(duì)消比之影響。
The prerequisite of actively mode-locked fiber laser stable work is that the modulation signal frequency must be the integral multiple to the cavity resonance frequency.
但由於主動(dòng)鎖模光纖激光器腔內(nèi)有較長的光纖，而光纖的長度極易因外界環(huán)境的影響而發(fā)生漂移，因而調(diào)制頻率和腔長很難保持匹配。
The arithmetic formulas for sine wave, linear frequency modulation signal, V-style frequency modulation signal, white noise signal, reverberation signal and echo signal are given by their definition.
根據(jù)信號(hào)類型的定義，給出了正弦信號(hào)、線性調(diào)頻信號(hào)、V型調(diào)頻信號(hào)、白噪聲、混響和廻波信號(hào)的郃成公式。

AM radio can be sent over larger distances, but the quality of the sound is not as good as a later kind of radio signal processing, called frequency modulation.
